RAZOR-BLADE HOLDER.

Application filed March 28, 1921, Serial No.456,294. Renewed January7,1924.

Fargo, in the 'county'of Cass andState' of North Dakota, have invented anew and useful Improvement in Razor-Blade Hold ers, of which thefollowing is a specification.

My invention relates to holders for safety blades used in stropping thesame upon an ordinary razor strop and particularly to the type of razorblade holder which comprises a pair of clamping members pivotallypositioned within a handle and has for its object to provide means forpivotally mounting said clamping members within the handle so that thesame can readily be assembled. 7

Another object of the invention is to provide means whereby the clampingmembers may be normally held in spaced relation to permit the readyinsertion of a safety razor blade between the same and to arrange thesemembers within the handle or holder so that the same may bepiv oted upona portion of the handle which serves as a fulcrum and so that saidclamping members may be easily removed.

Another object of the invention is to provide the member [adapted tooperate the clamping means with suitable stops whereby said member isheld in either its operative or inoperative position.

In carrying out my objects I provide a pair of clamping membersinsertable within a slot in the handle or holder of the device. Thesemembers are provided with notches adapted to engage a numberotprojections,

formed within the opening in the handle to be pivoted thereon saidprojections having notches adapted to receive flat sprmgs positionedbetween the said clampingmembers to normally hold the same apart. In

providing the stop mechanism for limiting the movement of the actuatingmember for said clamping members I provide a stop secured to the spindleoperating said actuating member, whichstop is movable with in a recessand is adapted to'engage the end walls of said recess when said splindlereaches its required'position in the operation of said clamping means.

The full objects and advantages ofmy invention will appear in connectionwith tional view of the part shown in Figure 1 and similar thereto, witha. portion of the device cut away and with the clamping members shown inengaging position.

Fig. 3 is a cross sectional view taken on line 38 of Figure 2 with theclamps shown open.

Fig. 4 is a cross'sectional view taken on line 4. l of Figure 2. I Y

Fig. 5 is asectional view taken on line 55 of Figure 2 with certainparts removed. Fig. -6 is a cross sectional View similar to Figure 3with the clamping membersin operable position. I

Fig. 1s a slde elevational view of a portion of one of the clampingmembers of the device. v a In Figure l, I have shown my invention tionof the same, in which opening are 1n' sortable two razor blade clampingmembers H and 15 as best shown in Figure 3. Adja- 7 cent theother end 17of handle 10 the same is formed with a rotatable extension 18 thereof bymeans ofwhich thesaid clamp ing members 14: and 15 may berenderedeffective or ineffective at'will in a manner to be presently described.

The exact COIlSlZIllClZlOIL of the clamping members 1a and 15 and themounting of the same withintheend12of handle 10 is best shownin' Figures2, 3, 5 and 7, at the extreme endsof the slot 13, as best shownin'Figure 5; the metalof portion 12 ofthe handle 10 isturnedinwardly at19 and 20 to form two inwardlyextending oppositely facing flanges.Thesefianges are adapted so. in its entirety which comprises-principallybe slid over to its operating position where-.

When themembers14 and 15 are in place within the device aid members as sume thepositions indicated in Figure3, said members being held in place on saidflanges in a manner to be presentlyde scribed.

F or holding members 14 and 15-in-spaced relation to one another Iprovide two spring clips-23-=eachqof which is provided with a circularhead 24 and two-upwardly ex-tend-- ing arms 25 and 26; These springclips are adapted to be inserted in recesses'27 and 28 formed in theflange members 20 and'19 in a mannerclearly shown in Figure 3 so thatthe head 24 thereof falls below said flanges-19 and 20 andso that thearms'25 and 26 engage:- the inner=portions of'the clamping members 14and 15 tending-ta spreadthe same apart abovethe flanges 19 and 20,thereby. causing: said clamping members to be oscillated upon theedgesof the opening 13 which serves-as fulcrumsfor the oscillation-ofsaid clamping'members 14 and 15, bringing the lower portions of saidclamping. i members v within the po1'tion 12 of "handle 10 together andcausing- ;the outwardly exposed portion thereof to be-spreadapart :asclearly indicated in Figure 3. 1 By 1 means of projections 29 and-30formed on the flange members 19 and 20 between rccesses 27 and 28accidental displacementot the spring; clips 23 -is "prevented. 7 Thesame are-furtherpreve'n'ted from fallingout o1- the-deviceby meansof thehead 24 which engages theunderside of theflange members 19 and 20adjacent the recesses 27 and 28.- When-the arms 25and 26 ofsaidspring.

clips are forced together the head 24 is reduced} inbreath suflic-ientlyto permit-the: insertion: of the same into the device :while after saidarms are agzfiin expfanded said head simultaneously expands and becomeslarge enough so that the spr1ng clip cannot be Withdrawn throughtherecesses27 and '28. With the spring-clip ;23dn-operation theclampingnwmbers 14 and 15 i are held 1 seated upon the flanges 19 Y and20 whioh serve to -hold thesam'e in proper position 1 Within theopeni11g;.,13- sothat the entire: edges ofsaid-opening engage. the Isides of i said members 14 and 15 servingias fulcrulns After 7 for theoscillation thereof as previously specified;

The device for operating the clamp members 14 and 15 comprises a spindle11 which extends through'out the entire length of the handle 10 andisjou'rnalled in ends 31 and 32 thereof. This spindle is normallycircular in cross section but has a cam portion at 33 positioned betweenthe lower ends of the-clamping members 14 and 15 which is elliptical incross section and is adapted to spread the'lower portions'oi? clampingmembers 14 and 15apart as indicated in Figure 6 when said spindle isrotated. At the'extrelne end of spindle 11 is attached the head 18previously referred to which conforms in shape to theend 17 of handle 10sothat when said headis positioned as shown in'Figur'e 1 the handle andhead have a continuous ap'earance. lVhen the holder is in operableposition and the elliptical cam positioned as indicated in Figure'ti thehead 18 assumes the position inditated in Figure 1. It can 'be'readilycomprehended that when a safety. razor blade 'is inserted betweenclamping members 14 and 15 as indicated in Figures 1 or 6, and the head18 rotated to cause-the cam member'33 to operate members 14 and 15 thatthe same oscillate upon the edges of slot 13 asfulerum drawing the broadends of'said members together to securely clamp the safe'ty razor bladeas distinctly shown in Figure 6; In this manner the blade isfirmly'hel'd while the same may be stropped upon an ordinary, razorstrop in a manner identical jw'ith'thestro ping of the ordinary form" ofrazor.

For terminating the movement of head 18 relative to the handle 10, 1provide'a stop 34 which is fori'ned on the end of "spindle' 11 adjacentits" attachment to the head 18. As beforestat'e'd,spindle 11 isjournalled inan opening 35for1ned in the extreme end 31 of'handle 10.'-'The stop. 34'is operable in an enlargement36 of the opening and"isadapte thtoengageside walls 37 and-380 fsaidbpening w'lien said head 18reaches positions shown in Figures 1 and 2.;"I1'1asn'iueh as theperiphery of opening 36 is'concentriowiththat of opening 35 and inasmuchas thecirculan portion of spindle 11"engajg es opening 35 andthe end ofthe stop 34 enjga'ges' the circular opening 36 the .7 said spindle 'ishence suitably journalled in the-end'31'ofhandle 10,1sothat the samemaybe properly rotated 'to operate upon the clamping. members 14 and 15Through the opening-3. 35 enlarged as indicatedat- 36, I the entirespindle including the elliptical cam member 3 33" may; be removed-(fromthe. device. For holding this spindle in place'I tlnead-theextreme endoftl1e--- same ;at"39 and provide a nut 4O which is adapted tobe-screwe'd upon the place nut 40 is screwed upon the threaded end ofspindle 11 and the entire device is firmly held in place.

The advantages of my invention are manifest. The device is extremelysimple in construction and operation and the clamping members adapted togrip the safety razor blade are very effective, thus making the devicehighly practical. My improved holder may be used upon any of the formsof safety razor blades so as to hold the same in proper position forefficient stropping. When a double edged blade is used the same may bereadily reversed within the holder without damaging the edge which hasal-..

ready been stropped. The device is extremely neat and attractive inappearance and can be economically constructed, the parts being easilyconstructed in great numbers and readily assembled within the holder.

In accordance with the patent statutes I have described the. principlesof operation of my invention, together with the apparatus which I nowconsider to represent the best embodiment thereof, but I desire to haveit understood that the construction ShOWn is only illustrative and thatthe invention can be carried outby other means and applied to uses otherthan those above set forth within the scope of the following claims.
